aroma-WINDOW smrie'oa'r.`

My invention relates to storm-window supports and has for its object to provide means for holding a storm-window .which is hingedly connected at its top in any desired angular position for openmg the same to a greater or less degree, said holdlng means operating automaticall to hold the same in any of the said positlons.

. The full objects and advantages of my 1nvention will appear in connectlon with the detailed description thereof and are particularly pointed out in the claim.

In the drawings, illustrating the application of my invention in one form- Figure 1 is a sectional elevation of a storm-window having my invention applied thereto when in-closed position. Fig. 2 is a view similar to Fi 1 with the window open. Figs. 3 and 4 are fragmentary views of the holding means showing how the same is secured to the sash and jamb, respectively. Figs. 5, 6 and 7 are detail viewsv showing the manner of constructing the frictional joint. Figs.l 8 and 9 are plan and sectional side views of a different form of joint connection of link 20` with plate 16.

As shown, Vthe Astorm-window 10 .1s hi'ngedlk suspended,as indicated at 11, .1n a wellown way. The holding devlce comprises a plate 12 which is secured d1- rectly to the side of the sash 10 by screws 13, asbest shown in Figs. 3' and 4. The plate 12 carries a lug or bracket 14 extending at right angles thereto to which is pivotally secured an arm or link 15. A second .plate 16 is secured to the side of the jamb by means of screws 17 as clearly shown in Fig. 4, said plate 16 having a toe piece 18 extending at right angles to the plane of plate 16, which toe piece is engaged by a spring catch 19 se-v cured vto plate 12 whereby the window is held locked when the same is closed. A link or arm 20 is pivotally connected to plate 16, preferably by means of a large screw 21 f Specification of Letters Patent. Patented Sept. 30,1919,` Application tiled December 9. 1915.

which extends through said plate and into the body of the jamb. The links 20 and 15 .are pivotally united at 22 b lmeans of a frict1on joint, which will hol said links in any desired relative position. As shown in Figs. 1, 2 and 5, this joint may comprise al -I series of registerin indentations 23 in the engaging body of t e arms 15 and 20 held in engagement by means of a rivet 24. As shown in Figs. 6 and 7, an additional spring washer 25 ma be employed, if desired, whereb a'yiel ing pressure may be exerted upon t ve registering indentations 22.

As shown in Figs. 8 and 9, the plate 16 is provided with a key 26 which is pivotally connected to the-plate 16. The key 26 has,

a tongue 27, and the arm 20 has an aperture 28 corresponding in size and shape to the key 26 and tongue 27. When sald ke is turned in one direction, as indicated in ig. 8, the arm 20 may be applied thereto; and

when the key .is turned into the dotted-line` position it will be effectively held where placed.

. The operation of mydevice will be ap-4 y parent when the storm-window is ful closed, -as shown in Fig. 1. The arms-"'15 and 20 will hang parallel with the sash al'on the-inside of the j amb and the catch 19 will ook over the toe piece 18 to hold the storm-window closed and locked. When it is desired to open 'the window .the catches 19 will be lifted, and it is only necessary t9 push out the bottom of the window to the extent desired. The links 15 and 20 will be moved at the joint 22 and the friction of such joint will hold said links wherever set, which, in turn, operate to hold the window at any v'desired angle. It is simply necessary to push the window out or pull it in to open the same to the extent desired. It has been found in practice 'that wind has no eiiectv cured to the storm window, a s ring catch connected with the upper end o said plate,-

a lug projecting from said plate toward the window frame, a pivoted to said lug,-

e. plate secured m the Windowiame, e link plete, said pivoted to seid last mentioned l links being pivoted to each other ends remote from their 'pivotal to the window frame and lstorm and a toe piece projecting from th said last mentioned plate, said toe ing adapted for engagement by sai attechment catch closed. at their window, e topA of ieee bespring when hef` s'torm windo'w is fully n In testimony whereof I ax my signature 1n presence of 'two witnesses.
